` SAMUEL S. FRETZ, OF PHILADELPHIA, PENNSYLVANIA.

GEAT FOR UMBRELLAS.`

SPECIFICATION forming part of Letters Patent'No. 694,957, dated March 11, 1902.

Application filed October 10,1901

T0 @ZZ 10h/0m, it may cm1/cern:

Be it known that I, SAMUEL S. FRETZ, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Uinbrella-Frames,0f which the following is a specification. l

My invention appertains to the joint between the stretcher' and the rib `and belongs to that class of joints in which the two opposite sides of the paragon rib are not rigidly secured to each other at the joint, but are allowed to spring toward and away from .each other and support the ends of the lap, which are folded in the inside of the stretcher, so that they will furnish a springing side bearing for the end of the stretcher,' clamping it firmly enough to prevent any appreciable lost motion at the hinge-joint and so making the umbrella very rigid, but at the same time allowing any sudden strain to be relieved by the springing of side walls. In my application No. 59,962 for a device of this class there was but two objections in certain classes of umbrella-frames. In that application the pivot-pin penetrated one side Wall' of the rib and stopped either directly Yafter passing through the end of -the stretcher or after passing through the inside fold of the lap. The first-mentioned construction had this practical difficulty, that a sufficient bearing for the pin was not provided in all cases, and the second-named, that the pin, being driven inand abutting directly upon the highly-tempered steel of the rib, was liable at times to crack it. This was peculiarly objectionable because these cracks were not readily seen, and the rib often was-made up into an umbrella before they were discovered.

In my present invention I carry the pin through both side Walls of the rib, but not through the outer fold of the lap, and abut it against the inside of this outer fold.

Describing now in detail the best means of which I am at present aware of embodying my invention, Figure vl is a plan view of my invented device. Fig. 2 is a cross-section of the same on line n; a: of Fig. I.

The rib A is of the ordinary paragon construction, and the lap Bis folded around the belly of the rib, and the ends 3 3 thereof are folded inside of the side Walls 5 5 of the rib to SerialNo. 78,210. (No model.)

form the side bearings for the' end of the stretcher. holes C C, through which the pivot-pin D passes. The pin D passes also through the end 7 of the streicherE through its reinforce F. The end 7 of the stretcher E,andpreferably also the reinforce F, are attened to give a broader bearing-surface to t against the side bearings formed by theinside of the inwardlyturned ends 3 3 of the lap B. The pin D passes through the outside fold of the lap folded around the rib, through the side wall of the rib, and buts against the insidefof the lap at the side of the rib opposite to that at which the pin was entered. The pin is then secured in place by giving it a blow or other suitable means being employed. The pin vcan either be secured fast to one side wall of the rib and the stretcher turn upon it, or it can be secured to the stretcher and turn in bearings in the side Wall of the rib,or be free to turn in either. It, however, should not be secured fast to both side Walls of the rib, because by so doing the elastic springing of the side walls of the rib is prevented.

I-Iaving now1 described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of a'paragon rib, a lap surrounding the belly'of said rib, and having the ends thereof folded inside the side Walls of said rib, said rib being provided with holes in the side walls opposite each other and the portion of the lap folded outside one of the side walls being provided with a hole registering with the hole in the side Wall of the rib, and the outside fold of the lap adjacent to the opposite Wall of the rib being integralg.

a stretcher having a.y flattened end inserted between the ends of thelap and a pin penetrating the side Walls of the rib and abutting against the inside-wall of the said integral fold of the lap, and free to move inward and outward in the side wall of the rib enveloped by the integral fold of the stretcher; substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses. l
